My grandparents are far less racist than their parents were
according to whom?
According to my grandparents. I guess it's possible they weren't less racist, but they definitely weren't as vocal about their racism.
My children are going to grow up with black cousins. They are going to have access to television and the internet where there will be a mixture of faces. They will have many different races represented in their schools.
Everyone thinks I'm naive, but do you honestly believe that our children and grandchildren will be as racist as our parents?
The way we end racism is by choosing not to repeat the mistakes of those who came before us.
Unless, of course, you believe that racism is a natural human tendency.
